We provided four cordless phones which could all receive and make outbound calls at the same time, this has increased productivity for staff allowing simultaneous calls as well as flexibility to move around the office whilst taking/making calls.
If staff members are out at events calls would automatically go to a designated mobile and if busy would go to voicemail to email. Once a voicemail is left the recording is sent via email so they can pick up the message anywhere.
A door phone was installed outside the building which connects to the telephones allowing staff to see who is at the door before answering.
